I don't get why A is wrong. It seems to me like both A and B could be right.

Do you go to UT Austin ?

Answers A and B show the same orientation of the structure, but only B has the correct face (the house looking thing), which appears in the bottom left of the unfolded pattern.

It won't allow me to upload anything bigger than that image.

if you upload it to photobucket and copy then paste 'img link' into the thread there will be a bigger image

make sue you use the IMG LINK because the picture is still small..if you put a mouse over the uploaded picture in your photo album, in the right hand corner a little thing will appear click on it and there will be various links use the last one its called img

rotate the question 90 degrees so that the portion highlighted in red will be the base of that view...now look how after you rotate, the top angle is now facing left. In A that angle is facing in the right direction and there is no way to turn the figure to make it face left..does this make sense?

the front view in A should be in the same orientation as the front view in C, but C is wrong because the white portion of the little square should touch the frontview not be away from it

if you play with the explanation (the one on the bottom that's already folded) you will see that there is no way to put the front view on the red base that i have highlighted and make the top angle face in the right direction

simply, always fold the thing into the paper (not out of the paper)
There is no way that you can get the front face of choice A because it is not same as what you have in the unfolded one. (it is mirror image of what you have, like enantiomer)

i think this is a way better explanation 😉 mirror image it is 🙂
